Do you say thanks or thank you?

Depends on what its for...if its something small I say thanks, if its something big I say thank you, if its something HUGE, I say Thank you very much.

It depends on the situation. I say thanx when its more casual..

If my friend buys be a coffe then I say "thanx"

If I get a laptop for my birthday I say "thank you"

=D

I usually say thank you

I say thank you.

I usually say,Thank you.

When speaking= thank you or thanks

When typing= thnx, thx or ty

Thank you for these points.

I use both it depends on the situation

well when i say "thanks" its more of a casual thing that just naturally comes out. but if it's with enthusiasm, or i'm trying extra hard to be polite, then i say "thank you"

:)

I say both .. it just depends on who it's to .. and why.
